Tax lawyer in Lyon,
international and private wealth taxation
A fresh reading of your situation, across borders and generations.
Firm founded by Lalé KilicA method in three movements
International private wealth taxation is not handled in isolated steps. We approach each matter in three movements that feed into one another.
Take stock
- We analyze your wealth, tax and family situation as a whole.
- We identify missed filings, misapplied tax treaties, and unbalanced structures.
- We restore your compliance before taking any further step.
Align
- We align the international tax treaties and the French regimes that apply to your situation.
- We activate the mechanisms suited to your wealth, your family, your project.
- We secure or redesign the structures that hold your wealth.
Anticipate
- We build your wealth architecture over five, ten, thirty years.
- We prepare the sale of your business, the transfer of residence, the transmission of wealth to your children.
- We remain by your side as your situation evolves.
Our practice in international private wealth tax law
French-Swiss taxation
You manage wealth between Lyon and Geneva, you are preparing a transfer of residence to Switzerland ahead of a sale, or you are inheriting across both countries.
- Transfer of residence, exit tax deferral and choice of canton
- French-Swiss inheritance since the end of the tax treaty in 2015
- Taxation of cross-border workers, the 2026 remote-work amendment and social security agreements
French-American taxation
You are an American living in France, you hold assets or accounts in the United States, or you are inheriting from a US trust.
- FATCA, FBAR and reporting obligations to both tax authorities
- US trusts, IRA, 401(k) and RSUs while resident in France
- Inheritance and gifts between France and the United States
International estate planning
Your heirs or your assets are spread across several jurisdictions, you want to plan ahead for a complex transmission, or you need to resolve a deadlocked estate abroad.
- Applicable law, treaties and conflicts of jurisdiction
- Forced heirship and foreign legal regimes
- Coordination with notaries and advisors in other countries
Business owner’s wealth
You are preparing a sale, structuring a family transmission, or weighing whether to stay in France or settle elsewhere.
- Contribution-and-sale, the Dutreil pact and the tightening of the 2026 Finance Act
- Holding company structuring and the new tax on wealth-holding companies
- Exit tax and the timing of the sale and the transfer of residence
In practice, a situation often spans several of these areas. We look at them together.

Nearly twenty years of practice in international private wealth taxation. A first career in major American law firms in Paris, before founding L.L.V. FIDEUROPE AVOCATS in Lyon.
“ I don’t handle a file. I accompany families across several generations. ”
My clients come from France, Switzerland, the United States. Many arrive once their situation has become complicated: a poorly prepared move, a missed filing, an inheritance no one had anticipated. Others come earlier, to structure ahead of time.
My firm, L.L.V. FIDEUROPE AVOCATS, works in close coordination with notaries, private bankers and advisors in other countries on cross-border matters.

Before you book a consultation
A few answers to the questions that come up most often in a first meeting, so you can arrive prepared.
01 When should you consult a tax lawyer in Lyon? +
There are four decisive moments. Before a transfer of residence abroad or a return to France, to anticipate the exit tax and ensure compliance. When selling a business or planning a significant transfer of wealth, to structure things in advance. When an international succession opens, to identify the applicable law and coordinate the jurisdictions. And always, if you receive a letter or an audit notice from the tax authorities, to defend your rights methodically.
02 I’m moving to Switzerland. When should I consult you? +
Ideally, before you leave. The earlier we work together, the more we can secure the exit tax deferral, choose the canton suited to your wealth, and prepare compliance in both countries. If you have already moved, we take your situation as it stands and restore whatever can be restored.
03 I’m an American living in France. Do I really have to file with both tax authorities? +
Yes, and this dual obligation is rarely well understood. US citizens and permanent residents remain taxable in the United States regardless of where they live. We align your French taxation with your FATCA and FBAR obligations to avoid double taxation and penalties.
04 An international succession has opened. Where do we start? +
By identifying the applicable law, which depends on the deceased’s residence, the location of the assets, and any provisions in the will. This analysis shapes everything that follows. We then coordinate with the notaries and advisors in the other jurisdictions.
05 I’m preparing to sell my business. When should I consult you? +
At least 18 to 24 months before the sale. That is the window to structure a contribution-and-sale, activate a Dutreil pact where relevant, or anticipate a transfer of residence. Later on, the options narrow.
06 What happens in a first meeting? +
We take an hour to understand your situation as a whole: your wealth, your family, your plans, your constraints. No jargon, no hasty promises. We tell you what can be done, what cannot, and the way of working that suits you.
07 How do your fees work? +
Fees are charged on an hourly basis or as a fixed fee, depending on the nature of the matter, with a written fee agreement before any engagement. We set out the cost and the scope clearly from the first contact, with no hidden charges.
08 How do you guarantee the confidentiality of my files? +
Professional secrecy applies to every piece of information exchanged, including anything you send us before signing an agreement. Our working tools are chosen so that no client data ever leaves a secure perimeter. Confidentiality is not an option; it is the very condition of our profession.
09 I’ve received a letter from the tax authorities. Is it urgent? +
Most likely yes, especially if it is a request for information, a proposed tax reassessment, or a formal notice. Contact us quickly, ideally within the week. The sooner we step in, the more room we have to respond within the deadlines and to negotiate.
10 How does your role differ from that of my accountant? +
Your accountant prepares the filings within the framework of the law. The tax lawyer builds the strategy upstream, defends your position before the authorities, and is legally accountable for the recommendations made. We often work hand in hand with your accountant, each within our own field.
A first conversation, with no obligation, to understand your situation.
